‘A'isha said

We went out with the Prophet (ﷺ) at the Farewell Pilgrimage, some of us raising our voices in the talbiya for an ‘umra and others for a hajj. When we came to Mecca God s messenger said, “Those who have raised their voices in the talbiya for an ‘umra and have not brought sacrificial animals may put off the ihram, but those who have put on the ihram for an 'umra and brought sacrificial animals must raise their voices in the talbiya for the hajj along with the ’umra, and not put it off till they do so after performing them both ; (a version has “and not put it off till they do so after sacrificing their animals”) and those who have raised their voices in the talbiya for a hajj must complete their hajj." She said: I menstruated, and did not go round the House or run between as-Safa and al-Marwa, and I continued in my courses till the day of ‘Arafa. I had raised my voice in the talbiya only for an ’umra, but the Prophet (ﷺ) ordered me to undo my hair, comb it, raise my voice in the talbiya for the hajj, and let the ‘umra go, which I did, and performed my hajj. He sent ‘Abd ar-Rahman b. Abu Bakr along with me and ordered me to make an ‘umra in place of the one I had missed from at-Tan‘im. She said: Those who had raised their voices in the talbiya for the ‘umra put off the ihram after making the circuit of the House and running between as-Safa and al-Marwa, then made a circuit after they returned from Mina, but those who combined the hajj and the ‘umra made only one circuit.
